Do You Know About DallasMod.Com? shows the famous Round House listed for sale.  A masterpiece of design, the Round House's architectural plans were originally done by Bruce Goff and carried out by one of his students, who built it off of Royal and Hillcrest back in the 60s. I learned this bit of info after interviewing the homeowners 10 years ago, who were responsible for bringing it back to its original mad, mod glory.
